ECOSS

The Best Choice in Evaporative Cooling

The Güntner ECOSS stainless steel evaporative condenser product line is proof of our ecological commitment to environmental and industry concerns and enables us to offer a product that will exceed the expectations of the facility owners, operators, and installers.

Highest thermal performance

lower operating costs

lower maintenance costs

lower installation costs

Galvanized coatings for evaporative condensers have been used in industry since the 1950s. A lot has changed since the 1950s. More stringent environmental discharge concerns have led to the reduction or elimination of effective chemicals in both the galvanizing process and in water treatment programs. Facility owners need to consider water usage restrictions, source water quality, discharge permits, and which chemicals they are willing to allow at their prospective facility site prior to making any investment decision.

The ECOSS stainless steel evaporative condenser product line makes these decisions a lot easier.Stainless steel coils and casing do not leach zinc or lead into the water system, do not require costly and time consuming passivation treatments, and do not risk the occurrence of premature failure due to “white rust”. They do offer superior corrosion resistance to reduce water and chemical usage, a reduced propensity to scale on the smooth walled stainless steel, and a more forgiving material for long life even when faced with eventual water quality “upset conditions.”

The benefits of the ECOSS stainless steel condenser are leveraged using the Güntner control technology which addresses the environmental and economic impacts of strained water resources. This eco-friendly control technology minimizes water treatment requirements and allows for operation at higher cycles of concentration, with reduced blowdown and lower make-up water requirements.

Güntner expertise in heat transfer design and stainless steel construction allows us to provide these benefits in a cost effective manner which boosts the return on investment for all-stainless construction to unprecedented levels. The total cost of ownership is reduced through long equipment life, low operating costs, low maintenance costs, and sustainable thermal performance, making the ECOSS stainless steel evaporative condenser the new choice in evaporative cooling.

Lower operational cost

Premium materials and components provide a platform to reduce operating costs by reducing energy consumption, reducing water usage, and reducing water treatment costs.

Intelligent Control System

- Güntner Motor Management as standard with EC fans- Selective fan shutdown- Easy integration into customers System- Record of all energy data- Messages and warnings are shown on controller display

Lower maintenance cost

Hinged fan nozzles, a service walkway located within the fan deck compartment, optimized perimeter access and a stepped basin design located on the side of the unit are just some of the features which make the Güntner ECOSS evaporative condenser a preference to service and/or maintain.

Direct Drive Fans

- Eliminate all routine maintenance- NO belt adjustments or replacements- NO belt sheaves to align or replace- NO greasing of bearings or replacement of bearings- NO replacement of drive shafts

Longer product life has arrived

The occurence of corrosive damage to galvanized steel condensers has increased dramatically in recent decades. Chromates have been all but eliminated and zinc treatments are restricted in many locations today. White rust damage to evaporative condensers and more specifically galvanized steel condenser coils is almost 5 times more damaging than it was 15 years ago. Galvanized steel surfaces must be passivated at start-up and routine maintenance intervals, requiring valuable man hours and associated chemical costs. Improper or no passivation at start up can destroy a galvanized steel condenser within a year.Stainless steel coils and surfaces are self-passivating!

Cold for meat processing plant

The Mexican food producer Qualtia Alimentos uses the refrigerant ammonia and an ECOSS evaporative condenser with a capacity of 1,500 kW in its meat processing plant’s primary circuit. The unit replaces a galvanized evaporative condenser. Chemical treatment of the cooling water is not required thanks to an osmosis system, and the EC fans and the GMM Güntner Motor Management save energy.

Rio Grande Food Park counts on ECOSS

The waste heat generated by produce storage of the US food production chain at Rio Grande Food Park is dissipated via two ECOSS units. The ECOSS evaporative condensers of the plant are part of the primary refrigeration circuit using the refrigerant R-404A. Altogether, the units have a cooling capacity of approx. 1.87 MW.

ECOSS for Cuauhtémoc-Moctezuma Heineken México

In the context of an energy efficiency directive, the Cuauhtémoc-Moctezuma Heineken México brewery opted for two ECOSS condensers for its central ammonia refrigerating circuit. Reconstruction works needed to be carried out at the building before the ECOSS units could be installed; the energy management upgrades of the plant resulted in total electrical energy savings of 1.5 MWh already during the first 5 months.

ECOSS 3000 in poultry slaughterhouse

The refrigerating plant of the Brazilian broiler slaughterhouse Frango Bomgosto in Brazlandia uses ammonia as refrigerant. An ECOSS 3000 serves as condenser that, compared to refrigerating plants equipped with standard technology, annually saves 6,000 litres of water and the related costs for operation. These savings are possible thanks to the Güntner Motor Management, partial-load operation and EC fans. The eco-friendly design also minimizes water treatment requirements.
